New features in Version 2.11 of CalculiX (check the documentation!)

Procedures

Speed-up of the treatment of SPC's and MPC's in the stiffness and mass
matrix.

Elements

Box, U and L-section beams were coded (Section 6.3.2. in the User's

of Applied Sciences for doing this).

Documentation

Expanded the documentation on gas networks.

CalculiX GraphiX

Changed menu function:
In the previous versions of cgx the "vMises" strain was calculated with
the same algorithm as used for the vMises stress. This is now corrected to
vMises_strain=2./3.*stressAlgorithm
